TYPE-WRITING -MACHINE.

SPECIFICATION forming part of Letters Patent No. 703,866, dated July 1,1902.

Original application filed March 2 1897, $erial No- 626,'724. Dividedand this application filed February 21, 1898. Serial No. 671,036. (Nomodel.)

' 625,724, patented February 22, 1898, No.

599,429, and relates more particularly to the construction and mode ofmounting of the paper-carriage.

My main objects are to provide alight and true running carriage and onein which'the weight of the carriage is supported upon roller-bearings;and my improvements consist in the various features of construction andcombination of devices hereinafter more fully described, andparticularly pointed out in the appended claims.

In the accompanyingdrawings, Figure 1 is a plan view of enough of atype-writing machine to exhibit my invention. Fig. 2 is a verticalcross-section thereof, taken at the line as x of Fig. -1, but showingthe top plate of the machine added; and Fig. Sis a detailedcross-section showing a modification of my invention, in whichantifriction-balls are substituted for the antifriction-rolls shown inthe main views.

In the several views the same parts willbe found designated by the samenumerals of 3 5 reference.

Referring to Figs. 1 and 2, 1 is the top plate of the machine, 2 theroller-carriage, and 3 the platen-carrier, pivotally connected theretoin a manner common to the well-known Remington No. 6 type-writingmachine. The roller-carriage at near each end is provided with aforwardly-projecting vertical plate 4, to which is pivotally attachedthe lower end of a link or arm 5, whose upper end is pivotally attachedto the rear of the platen carrier or frame 3 by suitable pins 6, alsoadapted to contact with either of two screw-stops 7 and 8, supported inears at the upper end of the plate 4. The front side of theplaten-carrier frame is provided with a supporting-roller 9, whichtravels upon a vibratory rail 10, at-

tached to arms 1O and adapted to be actuated by a shift-key (not shown)in the usual manner, whereby the platen-frame and its platen or roller11 may be shifted for upper-case Work. Normally the pins 6 rest againstthe screw-stops 8, at which time the platen is in position for printinglower-case characters; but when the shift-rail 10 is vibrated rearwardlythe platen-carrier and platen are moved in the same direction, and thepins are caused to strike against the stops 7, and at this time theplaten is in position for printing upper-case characters, the type-barshaving, as usual, each an upper and lower case type. When the shift-keyis released, spring mechanism returns the platen-carrier to its normalposition, with the pins 6 against the front stops 8. Theplatencarriermay be turned up about the hinge or pivotal points 12 of.its attachment to the links or arms 5 for inspection and correction ofthe work..

The roller-carriage comprises a horizontal top portion 13 and twovertically-depending portions or members 14 and 15, the former being thelonger of the two. 16 is a fixed rail for said carriage, secured tobracket 16, mounted on the top plate, and said rail has a horizontalbearing portion 17 and a vertical bearing portion 18. The under surfaceof the top member 13 of the carriage forms or is provided with a bearing19, which is opposite to and parallel with the bearing 17 on the rail,and the inner side of the depending member 15 of the carriage forms oris providedwith a bearing 20, which is opposite to and parallel with thebearing 18 on said rail. A vertically-disposed roll or diskv 21 travelson the bearings 17 and 19, and a horizontallydisposed roll or disk 22travels on-the bearings 18 and 20.

other, and there may be as many pairs as may be desired, two pairs beingshown. Each pair of rolls, as shown, is mounted in a holder The rolls ordisks "21 and 22 are arranged in pairs crosswise of each 23, with thepivots of the rolls arranged at right angles to each other, and theserollstantially the position illustrated. At the ends of the rollwayformed by the fixed rail and the carriage may be located stop-pins 24 toprevent the escape of the rolls. The rolls 21 sustain the verticalcomponent of the weight of the carriage, and the rolls 22 and 28 supportthe turning moment. In other words, the carriage is hooked or hung uponthe rolls 21, while the rolls 22 and 28 oppose its tendency to swingupon said rollers 21, and hence the forwardly-overhanging portion ofsaid carriage is prevented from sagging or tipping.

To prevent the carriage from rising and from tilting or rocking, it isprovided with a flanged plate or finger 25, which may be secured to themember 14 by a screw 26, which finger or plate enters a slot or groove27 in the other side of the fixed rail and travels therein during themovements of the carriage, but without contacting with the surfacesthereof. The said plate or finger is, however, arranged very close tothe sides of the slot or groove, so that it may immediately come incarriage 2 and also the weight of the platencarrier 3 when turned up arewholly sustained by the rolls 21; also, that the crosswise rolls 22,together with the roll or wheel 28, which may be mounted on a stud 30 onthe carriage 2, guide the carriage laterally-- that is, preventvibrations of the carriage in a horizontal plane; also, that the wheel28 and its track cooperate with the rolls 22 and the bearing-surfaces 18and 20 to steady the carriage in a third directionthat is, to preventthe carriage from rocking or tipping forwardly; also, that the plate orfinger and the right-hand wall of the groove prevent the carriage fromtilting rearwardly, and also that the said plate or finger and the baseof the said groove prevent the carriage from ris ing or from beinglifted from the bearing-rail. When it may become necessary to detach thesaid carriage, the flange plate or finger is of course unscrewed andremoved. The weight of the rear portion of the hinged platen-carrierwhen down in Working position, as shown at Fig. 2, is also borne by therolls 21, and the tendency of this weight to turn the upper portion ofthe roller-carriage forward is met and resisted by the crosswise wheel28 bearing against its track 29. When the platencarrier is shiftedrearwardly violently against the stops 7, the tendency to turn ordisplace the roller-carriage is met and resisted by the plate or finger25, and for the purpose of further obviating this tendency there may bearranged between the depending member 14 and the fixed rail a stop screwor device 31,

(one or more,) which may be secured either to the fixed rail or to thecarriage member 14.

Any violent forward shifting of the platencarriage against thestop-screws 8, which would tend to tilt or displace the roller-carriage,is resisted by the horizontal rolls 22 and 28.

In the modification illustrated at Fig. 3 I have shownantifriction-balls 21" and 28 instead of rolls or disks, the lower ballor balls 28 being arranged to travel in a V-shaped track 32 on the fixedrail and also on a beveled track or way33 on the carriage member 14,whereby the ball is properly supported and prevented from dropping out.The balls 21 preferably travel on plane bearings. The balls 21 sustainthe Weight of the carriage, as do the vertically-arranged rolls 21 inthe other views, and the said balls 21 also support or steady thecarriage horizontally or laterally, as do the rolls 22 in the otherviews, while the ball or balls 28 perform the function of the horizontalwheel 28 in Figs. 1 and 2. In other respects the construction exhib-.ited in Fig. 3 is similar to that shown in the remaining views.

In the use of the term roller-bearings herein I wish to include both theroll or disk form of Figs. 1 and 2 and the ball or spherical form ofFig. 3, althoughI prefer the former in practice.
